solubiltiy rules vs. f.p/b.p elevation

this is prally a realllyy stupid question but u know in when they ask you to fine the f.p or bp...of a nonvalitile solute i=1 and if it is a volatile solute meaning it will disassociate fairly easily i=2,3,4.etc depending on the cmpd.....HOWEVER does solubility rules of the product have to do nethien with this one like if you have NaOH i=2 howeve say if u had but say if u had something like MgOH2 which is insoluble would i=1?

No i=3 there, the i value has to do with how many it will dissociate into. i is the theoretical number of ions that the molecule will dissociate into.

if it says nonvolatile NaCl this disassoiciate so i=2

but what if it said VOLATILE NaCl would this make it i=1?

 

[jdent]

Im not understanding you so clearly. NaCl will dissociate into 2 ions.

 

[pistolpete007]

basically what would the solute have to be for it to be i=1

also does the word volatile/nonvolatile have nething to do with what i=

Sugars most organic componds dont dissociate in water, and therefore would have a i=1. Basically all proteins, sugars, non-electrolytes and organic compounds have an i-1.
Hope this helps
